LATCH FOR DOORS OR GATES.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed March 26,1907. erial No. 364,693.

To all whom it may concern:

Be it known that I, THOMAS P. WALSH, a citizen of the United States ofAmerica, residing at Grayslake, in the county of Lake and State ofIllinois, have invented new and useful Improvements in Latches for Doorsor Gates, of which the following is a specification.

This invention relates to latches for doors or gates, and one of theprincipal objects of the same is to provide a latch of simpleconstruction which can be operated from either side of the door or gate.

Another object of the invention is to provide a door latch which can beoperated from either side of the door and which can be locked againstoperation from the outer side of the door.

Still another object of the invention is to provide a combined latch andhandle which can be quickly attached to the door and door frame, andwhich will be composed almost entirely of metal straps and which will besimple in construction and inexpensive to manufacture.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a latch made in accordance with myinvention and shown from the outer side of the door, the door and theframe being broken away. Fig. 2 is a horizontal section, portions of thelatch and handles being shown in plan. Fig. 3 is a vertical sectionthrough the lock and keeper. Fig. 4 is a detail section showing thecatch for holding the door or gate open.

Referring to the drawings for a more particular description of myinvention, the numeral 1, in Figs. 1 and 2, designates the door, and 2is the door frame. Secured to the opposite sides of the door are thelatch members 3, 4. The latch member 3 comprises an arm 5, a handleportion 6 and a latch member 7 provided with an angularly bent shank 8having a latch head 9 formed thereon, said latch head having a curved orsemicircular outer edge 10 and oppositely disposed shoulders 11. Thelatch member 4 consists of an arm 5', a handle member 6, and afoot 7 Themembers 3 and 4 are secured to the door by means of a pivot bolt 12which passes through the members 4 and 5, through the door 2, andthrough an anti-friction sleeve 13, said bolt 12 being provided with anut 14 for securing the members together upon opposite sides of thedoor. A bolt 12 extends through the arm 7 and the foot 7 of the twomembers 3 and 4, and said bolt 12 is provided with an anti-frictionsleeve 13, a nut l4 engaging the bolt to hold the two members in placeupon opposite sides of the door. The sleeve 13 is mounted in a curvedslot 15 to permit the latch members to swing upon the pivotal bolt 12.A, suitable keeper 16 secured to the door 1 passes across the arm 7 tolimit the action of the same. In the door frame 2 a mortise 17 isprovided and secured in said mortise is a combined lock and latch keeper18, said latch keeper being provided with a curved inwardly extendingcatch tongue 19 adapted to engage one of the shoulders 11 of the latchhead, and to permit the curved portion 10 of said latch head to rideover the same when the door is swung to. The other shoulder 11 of thelatch head is engaged by the bolt member 20 of the lock 18.

As shown in Fig. 4, a catch 21. is secured to the side of a building ora fence 22 to engage the handle member 6 of the latch to hold the dooror gate open.-

From the foregoing it will be obvious that a door or gate latch made inaccordance with my invention may be readily operated from either side ofthe door or gate, that the latch is of simple construction, can beeasily connected to a door, can be manufactured at slight cost, and willbe found very efiicient and reliable in use.

Having thus described the invention, what I (3121111118 1. A latchcomprising a'handle portion, a latch head extending inwardly from theend thereof, said latch head having a curved outer edge and oppositelydisposed shoulders, in combination with a keeper having a curvedinwardly extending catch member.

2. A latch comprising a member having a handle thereon, an inwardlyextending latch head, a curved catch for said latch head, and a handlemember secured to the opposite side of the door or gate, said two handlemembers be ing' pivoted upon a bolt extending through the door or gateand connected together by a bolt which passes through a curved slot inthe door or gate, substantially as described.

In testimony whereof, I affix my signature in presence of two witnesses.

THOMAS P. YVALSI'I.
